Trolleybuses of Roma–Condesa

Most were Japanese buses that were donated to Servicio de Transportes Eléctricos by the Kansai Electric Power Company in Japan in 1994, for possible operation, which never came to fruition, and in 2000 they were repurposed by Cuauhtémoc borough in a programme to create educational centers.

)[2] Some were returned to use later as children's reading rooms,[7] but others sat abandoned in various parts of Mexico City, mainly still in the Cuauhtémoc borough.

[8] From 2000 and 2005, the three buses sat abandoned until Ariadna Ramonetti discovered them and worked to create the Galería Trolebús (Trolleybus Gallery) in cooperation with the Cuauhtémoc borough to promote non-traditional art projects.

[8][9] Artists who worked with the vehicles from 2005 to 2009 included Karen Cordero, Ana Elena Mallet, Santiago Espinoza de los Monteros and Antonio Calera.

[8] In 2006, Montiel Klint inhabited the trolleybus at the north end of Plaza Luis Cabrera in Colonia Roma, blocked from view for two months with only eight photographs on the outside of the bus for visitors to see.

[citation needed] The work consisted of covering the interior of the trolleybus with cardboard pieces on which phrases from young thieves whom the artists had interviewed were written.

[9] Alvaro Verduzco's work was called “Túnel” (Tunnel) in 2009, which used a cone made of cardboard with the bus to create the illusion of infinity.

[13] The work was part of a public art program called Haru ga kita (Spring comes) en México under this artist along with musician Emiliano Isamu.

It was parked as an art installation in the southern part of Parque México until early 2009, then moved east to Calle Toluca behind the Jardín Ramón López Velarde, where it remained until 2014.

5122, is an American-built Marmon-Herrington trolleybus whose chassis was built in 1948 but which was retrofitted with a new, modern body – with a slanted front end shape – in 1993 by a company named TATSA (Tanques de Acero Trinity S.A.).
